Take a pic of where the leak is and we can advise on the usual suspects, it's too vague saying it just leaks, there are a number of areas prone to leakage and we need to isolate where it's coming from.
Are you sure its not the end cap O rings that are leaking? they are very, very prone to it.
It's the oil gallery O-Rings, most likely because aftermarket head gaskets are thicker than Honda ones and they don't appear to make the O-rings they supply thicker to compensate for that, so they crush like they should and end up leaking.OE gasket will solve it unless there is some damage to the surface but then why both ends at the same time?
